- Jesse Pinkman: Look... look, you two guys are just... guys, okay? Mr. White... he's the devil. You know, he is... he is smarter than you, he is luckier than you. Whatever... whatever you think is supposed to happen... I'm telling you, the exact reverse opposite of that is gonna happen, okay?
- Skyler White: [on the possibility of Walter killing Jesse] We've come this far for us. What's one more?

- Kuby: Uh, Badger and Skinny Pete. Yeah, no, he's not with them.
- Walter White: They could be covering for him.
- Kuby: I posed as a meter reader. I put a bug in the tall kid's mom's place. For three hours straight, all he talked about was something called Babylon 5.
- Walter White: You're full of colorful metaphors, aren't you, Saul? Belize, Old Yeller. Just brimming with advice. Do not float that idea again.
- Walter White: Jesse is upset about the boy. I just need to explain to him why that had to happen.
- Saul Goodman: Okay, but say, for the sake of argument the kid's not in the mood for a nuanced discussion of the virtues of child poisoning

- Walter White: Make him see reason.

- Walter White: No.
- Marie Schrader: Saxitotoxin. Derived from shellfish. Produces a flaccid paralysis that leaves the victim conscious through a progression of symptoms. Death occurs from respiratory failure. That is definitely a contender.
